New Technology Could Lead To 3D Printers

kdawson posted more than 7 years ago | from the chemical-origami dept.

Printer 62

nomoreself writes "PhysicsWeb reports that a team of scientists in Jerusalem has come up with a method for creating self-assembling 3-dimensional models from a single sheet of paper. The 'chemical origami' is created by etching a pattern of monomer onto the paper and then heating it. The chemical's reaction to the heat causes bends of varying degree in the paper, molding the sheet into the patterned model. A professor in the US with no apparent ties to the study says in the article that the technique could be used to create self-assembling prototypes, or even a printer that prints 3D objects."

God damnit, women love fucking doormats, but they only have sex with assholes. They want the doormat men to do their bidding, then they fuck an ass who would never dream of giving up their free time to help the woman move, and then wonder why the asses treat them so poorly. Or maybe I'm just drunk and misogynistic. Thank you OS X for teaching me how to spell.

That's rough. But if you knew doormats don't get laid, why'd you help her?

Also, I hate to be presumtuous, but is she good-looking and vacuous? Don't chase women like that, they're bitchy. Go after the smart and the nice ones, and don't judge based on looks (unless you can't get your arms around her - that's a self-control problem). I'm not saying you personally are hypocritical, but I find most ugly men want women to ignore looks, so that they can bang hot chicks. Doesn't make much sense.

Well, have I sufficiently pissed you off with my unsolicited advice? Wonderful! Now go get some hydrocodone, it'll make you happy. But don't get addicted. And stop worrying about women, most of them suck anyway.

Re:useful to a limited degree (1)

Quino (613400) | more than 7 years ago | (#18136716)

that's what I was thinking -- you can already get (and have been able for 20+ yrs.) "3d" printers that let you do quick prototyping. I've seen models that are even fairly small that can sit on your desk, and use plastic resins (that is, much more useful than paper).

Not only that, but you're severely limited in the geometry that you can produce if all you can do is fold paper ....

There might be a use for self-folding paper *pseudo* 3D printer like this, but I can't think of one of the top of my head ...

It's called stereo lithography, and generates plastic 3D models. It's been on the market for about 20 years, and has established a niche in the CAD industry.

Not much technical detail... (1)

RyanFenton (230700) | more than 7 years ago | (#18135426)

Thus, not much chance to evaluate the technical limitations of such chemical bending of paper.

In fact, here's the complete text of the article, since it's so short:

I'd definitely call this a paper bending toolset, rather than a paper folding toolset - fine distinction perhaps, but it doesn't sound as if you'd achieve the creased edges one would expect out of origami, but rather the bent edges of a wet piece of paper drying into a shape. I wonder what the real ranges of movement that are possible with such a tool, and the mechanics of designing a shape, and if cutting would be allowed in such a design. I'd presume all steps would have to take place at once - as after heating, being able to add new chemical stripes would be technically difficult. Sounds like a novel use of chemicals, if nothing else - it's just not enough information to do much more than imagine.

Googling for 'hebrew university chemical origami', here's a slightly more informative article:

http://www.rsc.org/chemistryworld/News/2007/Februa ry/22020702.asp [rsc.org]

Ah, the pictures there do actually help. So, this is what they meant by "sombrero structures" and the like. Fairly limited shapes, but the limited ability to combine them could have use in advertising or other cases where cheap simple paper shapes.

Ayup. Thanks for posting that. Could not wrap my head around what the 'printout' would look like from TFA.

Would be a cool way of making realistic looking ashtrays out of thick wads of flashpaper, provided the flashpaper + chemicals didn't fuck up a 2 million dollar printer.

If it's someone else's, fuck the printer. I wanna see what happens.

mabhatter654 (561290) | more than 7 years ago | (#18138350)

What they're doing is basicly 3d model UV mapping!!! When they mentioned how hard it was to map a 3d ink to a 2d surface the first thing I thought was looking at those streached and twisted quake3 character model textures... It would be like making little shrinky-dink models... sounds like fun!!

Finally 3d printers! (4, Interesting)

logicnazi (169418) | more than 7 years ago | (#18135876)

Oh wait we already have those.

Despite the bad description of why this is important it actually is pretty interesting. This sort of approach is much more efficient for creating 2d sheets with varied 3d geometry than traditional 3d printing which would have to build them up layer by layer and might not even have sufficient structural stability to make the object if it's too bendy.

What would really make this technique useful is if there was some way to combine it with more traditional 3d printing technologies. For instance if you could start with a nice curved surface like this and add layers that would be really cool. However, there are such serious problems with doing this that I think it is unlikely.

Frankly, while interesting I suspect this is just a sidelight in the development of 3d printing technology. What I want to know is why it is taking so long. When will we all have our own 3d printers? When can we shut down those vast numbers of assembly lines that make nothing but strangely shaped 3d objects?

Re:Finally 3d printers! (1)

logicnazi (169418) | more than 7 years ago | (#18135948)

To be clear I don't mean this technology will not have any useful applications. Rather it is more like those clear TFTs that have found use in plasma TVs. Useful in some areas but a sideline to the development of the computer industry or in this case the 3d printer industry.

Re:Finally 3d printers! (1)

Re:Finally 3d printers! (1)

smallfries (601545) | more than 7 years ago | (#18142502)

The "classic" 3d printers are cool for small models - no matter what you print they come out like unpainted minatures. They are really sweet for fabricating prototypes of shapes that are "hard" to make - 3d curves. They are useless for structural strength or the type of shapes that are "easy" to make.

This device looks like it can do the "easy" sructures, ie ones that fold out of a planar surface. It's another piece of the jigsaw, and I agree with you that the combination of the two technologies will become interesting. There is another vein of work; printing electronics. The idea these guys [newscientist.com] have been working towards is an open-source printer that can print itself. Essentially a weak form of a self assembling robot.

They've been covered on slashdot a few times before, and there is probably a more up to date news story somewhere. I remember that they were getting pretty close - they could print certain types of circuits and components, but were still working on the rest.

Also, it's not exactly "paper" they're printing on:


"We used N-isopropylacrylamide (NIPA) gels to construct sheets with inducible non-Euclidean gtar. The gels are produced by mixing NIPA monomers with bisacrylamide (BIS) (6% by weight of NIPA) cross-linker in water. The addition of catalysts initiates polymerization of a cross-linked elastic hydrogel [Supporting Online Material (SOM) text]. This gel undergoes a sharp, reversible, volume reduction transition at Tc = 33C (19), above which its equilibrium volume decreases considerably. Calibration experiments (fig. S1) using various homogeneous (each of a different fixed NIPA concentration) gel discs provide the relation between the monomer concentration and {eta}, the shrinkage ratio of the "activated" gel. These measurements show that dilute gels shrink a lot, whereas gels with high monomer concentrations undergo moderate shrinking."
